Working Principle
This facility enables researchers to perform highly sensitive, accurate, and reproducible quantitation of gene expression. The qRT systems can be used with TaqMan probe-based chemistry or intercalating dyes such as SYBR Green and is compatible with 96 wells, 384 wells. It monitors the amplification of a targetedDNAmolecule during the PCR, i.e. in real-time, and not at its end, as in conventional PCR. Real-time PCR is carried out in a thermal cycler with the capacity to illuminate each sample with a beam of light of at least one specified wavelength and detect the fluorescence emitted by the excited fluorophore. The two common methods for the detection of PCR products in real-time PCR are: 1 non-specificfluorescent dyesthatintercalatewith any double-stranded DNA, and 2 sequence-specificDNA probesconsisting ofoligonucleotidesthat are labelled with afluorescentreporter and quencher which permits detection only afterhybridizationof the probe with its complementary sequence.
